Description

A washing machine tub

technical field

The utility model relates to an outer barrel of a washing machine, which belongs to the field of washing machines.

Background technique

Washing machine is deeply welcomed by consumers as a convenient and applicable household appliance. With the continuous development of the economy and the continuous improvement of living standards, new requirements have been put forward for the laundry quality of washing machines. During the use of the washing machine, the dirty water will be discharged along with the outer tub of the washing machine, but most of the current washing machines drain slowly, and the suspended matter in the dirty water is very easy to adhere to the wall of the tub, resulting in unclean drainage of the stolen goods. A large number of bacteria grow inside the washing machine, causing harm to the human body. In addition, the traditional washing machine drains slowly and takes a long time, which not only causes a large amount of suspended matter in dirty water to adhere to the barrel wall, but also seriously affects the washing efficiency of the washing machine.

In addition, due to the unreasonable design of the outer tub of some washing machines currently on the market, especially the unreasonable structural design of the bottom of the tub, the dirty water after washing cannot be discharged smoothly, and even the dirty water cannot be drained cleanly. The washing effect of the washing machine is greatly reduced.

In view of this, the utility model is proposed.

Utility model content

The purpose of this utility model is to overcome the deficiencies of the prior art, and provide a washing machine outer tub with strong sewage discharge capacity and fast drainage speed, which can completely discharge large granular foreign matter in the washing machine and prevent dirty water from accumulating.

In order to achieve this purpose, the utility model adopts the following technical scheme: an outer tub of a washing machine, including an outer tub body, the outer tub body includes a tub wall and a tub bottom, a drain port is arranged on the tub bottom, and the connection between the tub bottom and the drain port A sump is provided at the junction, and the joints between the drain and the sump are smoothly transitioned. During the drainage and dehydration process of the washing machine, the dirty water will be discharged from the drain port. Under the action of the earth's rotation, the dirty water will generate a large vortex in the sump before it is discharged from the outer bucket, and the vortex will affect the water in the bucket. Dirty water produces a large disturbance force, and the suspended matter in the dirty water will be discharged out of the bucket along with the dirty water, which prevents the suspended matter from adhering to the barrel wall of the washing machine, thereby avoiding the problem of unclean laundry.

In the aforementioned outer tub of the washing machine, the water collection tank is funnel-shaped, and the opening is retracted along the water outlet direction. The funnel-shaped sump produces a larger vortex than the traditional drain, generating greater disturbance in the barrel. The larger disturbance force can quickly discharge the suspended solids in dirty water. Improved drainage performance of washing machines.

In the above-mentioned outer tub of the washing machine, the water collection tank is arranged in the form of annular steps along the water outlet direction and is retracted step by step to the connection with the drain outlet, and the transition between stages is smooth. The sump of this structure can not only greatly disturb the dirty water in the barrel, but also speed up the drainage, which greatly reduces the degree of suspended matter in dirty water adhering to the inner wall of the barrel and shortens the The drainage time improves the washing efficiency of the washing machine.

In the aforementioned outer tub of the washing machine, the inner surface of the sump is 2 to 5 steps of annular steps, and the annular steps are retracted step by step along the water outlet direction, and each step of the annular step is gradually reduced and lowered. The inner surface and the joints with the bottom of the barrel and the drain are all smoothly and gradually lowered along the water outlet direction. The opening of the sump is larger than the opening of the drain, and a larger vortex is generated in the sump, which generates a greater disturbance force to the dirty water in the bucket and reduces the amount of suspended matter in the dirty water attached to the barrel wall.

In the aforementioned outer tub of the washing machine, the inner surface of the tub bottom is gradually lowered from the center to the tub wall along the radial direction, and the water collection tank is arranged at the lowest point of the tub bottom. The bottom of the bucket with this structure can reduce the resistance of dirty water discharge, avoiding the problem that the dirty water to be discharged is not clean.

In the aforementioned outer tub of the washing machine, the inner surface of the bottom of the tub is inclined along the circumferential direction, the center of the inner surface of the bottom of the tub is higher than the inner surface near the side wall of the outer tub, and the water collection tank is located at the lowest point of the bottom of the tub. Location. This structure can also reduce the resistance to discharge of dirty water, avoiding the problem that the dirty water to be discharged is not clean.

In the aforementioned outer tub of the washing machine, the sump is located near the intersection of the tub wall and the bottom of the tub, and the connection between the sump and the tub wall transitions smoothly and is gradually lowered. This structure can reduce the resistance to discharge of dirty water, avoiding the problem that the dirty water to be discharged is not clean.

In the above washing machine outer tub, the bottom of the tub is provided with an annular water channel close to the wall of the tub, and the sump is set on the bottom of the tub at the lowest position of the annular water channel. The annular water channel can play a role in converging the dirty water to be discharged, and the dirty water gathered in the annular water channel can be quickly discharged along the dirty water.

In the aforementioned outer tub of the washing machine, the annular water channel is arranged obliquely clockwise or counterclockwise along the circumferential direction, and the annular water channel transitions smoothly and gradually to the wall of the tub and the bottom of the tub. The slanted annular water channel facilitates the rapid discharge of dirty water.

In the aforementioned outer tub of the washing machine, the section of the annular water channel is U-shaped or V-shaped, and one side of the annular water channel close to the barrel wall transitions smoothly with the barrel wall; the other side of the annular water channel is smooth with the bottom of the barrel. transition.

After adopting the technical solution described in the utility model, the following beneficial effects are brought:

In the outer tub of the washing machine described in the utility model, in the outer tub of the washing machine described in the utility model, the sump provided at the connection between the drain port and the bottom of the tub can make dirty water generate a large amount of water in the sump. The vortex strengthens the turbulence of the vortex to the dirty water and speeds up the discharge of the dirty water, so that the suspended solids in the dirty water are discharged out of the outer barrel along the dirty water; in addition, the smooth transition of the lower structure at the bottom of the barrel also helps to speed up the dirty water discharge. The drainage speed of the water is improved, and the outer tub is guaranteed not to accumulate dirty water, which greatly improves the drainage performance of the washing machine.

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.
